STOVE.

Specification of Letters Patent No. 1,444, dated December 27, 183 9.

To all whom it may concern:

Be it known that I, GEORGE D. BoYon, of West Wareham, in the county of Plymouth and State of Massachusetts, have invented certain Improvements in Stoves for Cooking; and I do hereby declare that the following is a full and eXact description thereof.

Figure 1 in the accompanying drawing, is a perspective view of my stove, whichinits general form resembles many other cooking stoves. Fig. 2- is a top view showing portions of the dampers and other parts, as seen through the openings in it. Fig. 3, is a segment of my stove, giving a perspective view through the opening in the top front plate, the part Fig. 4, which divides it into two boiler holes being removed. Fig. 5, 1s a sectional view through the part marked by a dotted line Fig. 1. Fig. 6, is a tin cover adapted to the top of the stove, formlng an inclosure over the boilers, and which may be used as an oven when desired, but which may be raised up out of the way, in a manner to be described.

In Fig. 1, A, A, are two open ngs for stove pipes, B B being sections of said pipes, each furnished with dampers C, C. K and K is the top plate; J J, the hearth form ng a part of the bottom plate in the ordinary Way.

X, is an oven behind the fire chamber. In the back plate of this oven, there is a sl1d1ng shutter at It, adapted to an opemng through which any vapor may escape into the flue behind the oven. The flue through which the heated air passes around the oven from the fire chamber, opens into said chamber both above and below the oven, as shown at (Z, and 9, Fig. 5, said flue being governed by dampers in such a way as that the draft may be directed either above, or below, the oven, at pleasure.

D, D, Figs. 1, and 5, are two sliding dampers, or shutters, governed by the rods E, E; each of these shutters may be made to cover one half of the throat, or opening, cl, Fig. 5, leading from the fire chamber to the fine I, between the top plate of the oven, and the plate K; and thus to arrest the draft partially, or completely. Two other valves, seen at P, P, Fig. 3, and one of them at P, Fig. 5, are used for the purpose of changing the direction of the draft under the front boilers, which they effect by the peculiar arrangement of the apparatus, to be now described. Above the fire-chamber, there 1s, 1n addldoes not'reach to the front plate of the stove,

but terminates in the manner shown in F ig..

2, allowing a space for the heated air to pass up in front of a cooking utensil, which fills the opening in it and in the plate K. To the back edge of the plate 5, b, the valves P, P, are hinged, closing, when down, as shown in Fig. 5, a direct passage from the fire-chamber (L, into the upper oven fiue I. In this position, it causes the whole draft from the fire to pass up in front of the plate b, I), Fig. 2, and around the boilers, in its way to the flue I. When the valves P, P, are raised, so as to be in the position of the dotted lines Fig. 5, a direct draft from the fire-chamber to the fine I, is admitted.

O, O, are the handles for governing the valves P, P, which, in Fig. 3, are represented as turned up. In this figure, the boiler hole is shown as elongated by the removal of the part M, Fig. 4. Movable pieces for this purpose are well-known devices, but in those used by me there is a peculiarity of construction, rendered necessary in order to adapt them to my stove. The lower portion N, of the movable piece, Fig. 4, when in place, forms a part of the plate 6, b, dividing it into two boiler holes. The two plates, M, and N, are connected by a partition piece L, which partition is connected with the piece seen at L, Fig. 3, and With a corresponding piece in front, shown by dotted lines L the whole, when together, constituting a partition extending from the front of the chamments, immediately below the partition just described, by a plate shown at H, Fig. 1. This plate may be removed and replaced at pleasure, there being grooves, or projecting pieces, on the back plate of the firechamber,

and also onthe front or bottom plates, to hold it in place;

h, h, Fig. 5, is the back plate of the fire chamber, and the'oven.

In addition to the. valves, or shutters,

f an air space between it and above described, there is along, sliding shut} rear oven flue Q and to direct the'draft either below or above theoven, as has been before done in other stoves. This ishutter must be sufficiently long to extend from side between the plates K,"and?),the whole being constructed, and operating, substantially as to side of the stove,.or to whatever length the opening of the upper end of said flue may require.

Fig. 6, represents a cover oftin which is fitted to the top of the stove so as toinclose all the boilers; extending back to the front of the smoke flue,or fines, and serving, when theboilers are not in use, to convert the whole space inclosed'by it into an oven;

it has a door in front, marked S, and may,

if preferred, be furnished with other doors.

Isuspend this cover over the stove by cords attached to the loops 0, 0,0, andpassing over pulleys, with counterweights. T, T, is pipe, or flue, for carrying off the vapors from the interior of the case. The .parts T, T, T,

I make to slide one within, the other, like" telescope tubes, but loosely. The horizontal part T, slides up and down on fixed rods U,

U, having holes through itfitting these rods;

the part T is stationary, and enters the chimney; this, and the part being so cut' as to form a lap joint, allowing the latter to rise from and fall into, the former. By these devices, the cover, may be raised and lowered with great facility; special closeness is not required in the respective junctures, as the vapors have little tendency to escape from the tube.

What I claim'as of my invention, and desire to secure by Letters Patent, in the within described stove, is y i v 1.'The manner in which I have combined the valves, or dampers, D, D, and P, P, with the fire-chamber and upper oven flue, and with the partitions L, 'L, occupying the space herein set forth. do not claim the valves D, D, or the valves P, P, in their separate capacities, both kinds having been before used, but not, as I believe, in-combination with each! other, which combination is necessary to the proper government of my divided chambers. i

2. I also'claim in combination with the foregoing, the dividing of the fire-chamber into two parts, by the partition H.

3. I likewise claim the manner of constructing and combining the vapor pipe T,

T, with the tin cover, by means of the sliding joints, and the lap joint, the whole operating, substantially, as described GEORGE D. BOYCE. Witnesses: i
